It's not acceptable, it is just that the people in the target audience don't care.

I see, it's not acceptable. It's just that most people accept it.

The majority accepting something has nothing to do with whether or not that something is acceptable. This is the concept behind the idea of the tyranny of the masses.

The tyranny of the masses has traditionally been held back by enacting rules of law that the masses have no interest in. In this particular case, that would be consumer protection laws that the majority of consumers would not care about.

I'm not so sure if accepting it is the right term, they just don't care or even understand the concept of something else.

It's sort of like how privacy isn't a concern/issue for this latest generation that is getting online.
